This offer has been available for a few months. I'm not too sure when they're going to cut it. What's great about it is it can be also used if you want to buy exam vouchers. I used it to purchase 2 Practice and 1 Proctored Test for GPEN, it dropped the price down to about $749 if I recall correctly. Also do not forget about their 25% off deal until 10/26 below (Assuming you can pay early):

Alright. I don't want to register for the OnDemand or vLive modes as they don't fit into my budget. Well I guess, the only other option I have is to register earliest to avail the $150 discount atleast. Thanks for the quick responses guys.
